13 Claims.

This invention relates to cabinet door construction and more particularly to door construction employed in the manufacture of refrigerators.

Doors of this character ordinarily are formed of two sheet metal shells having insulation therebetween and with or without a frame connecting these shells at their edges and with a suitable -trim or finish for the contiguous edges of the shells.

It is an object of the present invention to provide a finish or trim for the edge of the door, which trim is of improved appearance, of reduced cost, of durable construction, and which will minimize heat leakage.

A further object of the invention is to provide a construction requiring a minimum of labor in assembling or disassembling and in which all fastening elements are concealed.

7 Other objects and advantages will be apparent from 'the following description taken in connection with the accompanying drawing, wherein,

Fig. 1 is a horizontal section of a door-con structed in accordance with the present invention and showing a cabinet in dotted lines;

Fig. 2, a slightly enlarged fragmentary detail of a. slightly modified construction; and

Fig. 3, a horizontal fragmentary detail of a ing of inner and outer sections l3 and I4 respectively. The outer shell or plate II has its edge curled around athin flange M of the outer frame member l4 against the inner surface of which flange l 4 a gasket I5 is adapted to be compressed and held in place by the frame section l3 and a finishing strip I6.

The framesections l3 and I4 are out to form right angular complementary surfaces, and the outer surface of the frame member I3 is inclined or beveled at an angle substantially corresponding to the inclination of the beveled door frame of a cabinet, as shown. To this inclined or beveled surface a finish may be applied in the form of a separate strip l6 having a pyralin coating I! as shown in Figs. 1 and 2; or the pyralin finish may be applied directly to the frame member, as shown in Fig. 3. The strip I6 lsfastened in place by concealed fastening means such as nails l8.

In the construction of a door such as that shown in Fig. 1 the door pan II is first formed of four frame members it which are applied one at each side of the door to form an annular frame section and the inner frame member l3 has the trim strip it applied thereto, whereupon the inner frame section I3 is applied upon the outer frame section 14 and is fastened thereto by means of screws or other fastening elements I9. The gasket l5 has its inner edge or bead l5 clamped in a groove l3 in the lowerouter edge of the frame member l3.

-In Fig. 2 the parts are identical except an inner frame member l3a of slightly modified con-' struction is provided, said member l3q having a groove I30. spaced slightly inwardly from the outer edge as is also the case in Fig. 3. The inner door plate or pan I0 is appliedlastly and is secured in place by fastening elements 20. It will be understood, of course, that the finish l6 for'the door is, like the frame, of nonheat-conducting material and the coating i'l therefor is of durable, resistant, heat insulating material as for example, pyralin, or the like, and it may be applied in sheet form or sprayed directly upon its base. a I

It will be obvious to those skilled in the art that various other changes may be made in the construction and arrangement without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawing and described in the specification but only as indicated in the appended claims.

What is claimed as new is:

1. Cabinet door construction comprising cooperating frame sections forming when assembled an annular frame, an outer plate carried by one of said frame sections, an inner plate carried by another frame section, anda gasket clamped by and between said frame sections and extending along the edge of the door.

2. A refrigerator door comprising inner and outer frame members, inner and outer plates carried by said frame members, a gasket clamped by and between said frame members, one of the frame members being provided with a beveled finishing surface and a protective sheath for said surface and giving it the appearance of a breaker 45 strip.

3. A refrigerator door comprising a door frame, inner and outer plates secured to the door frame, means for binding said plates together transversely of the door frame, and a non-hydroscopic 50 thin protective finishing member for the periphery of said frame.

4. A refrigerator door comprising a door frame, inner and outer plates secured to the door frame, means for binding said plates together trans- 65 versely b1 the as, a gasket clamped by and between portions of the door frame, a thin protective finishing member for the periphery of said frame and concealed means for fastening said protective finishing member in position.

5. A refrigerator door" comprising inner and outer metal plates, an independently formed marginal frame for each of said metal plates. said marginal frames being complementarily formed to overlap substantially parallel to and substantially transversely of 'said plates, the outersurface of one of said frames being tramversely beveled, said bevel being inclined inwardly from the outer plate toward the inner plate to provide a surface substantially parallel to the receiving opening of a cabinet adapwd to be closed by said door.

6. A refrigerator, door comprising inner and outer metal plates, an independently formed marginal frame for each of said metal plates, said marginal frame being complementarilyformed to overlap substantially parallel to and substantially transversely of said plates, the outer of said frames beingtransversely beveled, said bevel being inclined inwardly from the outer plate toward the inner plate to provide a surface substantially parallel to the receiving opening of g said marginal frames being complementa'rily formed to overlap substantiallyparallel to and substantially transversely of said plates, the outer surface of one of said frames beingtransversely beveled, said bevel being inclined inwardly from the outer plate toward the inner plate to provide a surface substantially parallel to the receiving opening of a cabinet adapted to be closed by said door. a protective sheath for said beveled surface, and concealed fastening means for securing said sheath in position. a

8. A refrigerator door comprising inner and outer metal plates, an independently formed marginal frame for each of said metal plates, said marginal frames being complementarily formed to overlap substantially parallel to and be closed by said door, a protective sheath for said beveled surface, concealed fastemng means for securing said sheath in position, and a gasket clamped in position by said sheath.

9. A refrigerator door comprising inner and outern etalplateaamarginalframeforeach a,ose,os1

of said tal plates, said marginal frames being comp ntarily formed to overlap substantially parallel to and substantially transversely of said plates, the outer surface of one of said frames being transversely beveled, said bevel being inclined inwardly from the outer plate toward the inner plate to provide a surface substantially parallel to the receiving opening of a cabinet adapted to be closed by said door, and a protective sheath for said beveled surface, said sheath being applied directly to said beveled 10. A refrigerator door comprising inner and outer complementary frame sections secured together, each of saidframe sections having a peripheral flange, the flange on the inner section extending substantially to the outer surface of the door and being beveled to correspond to the inclination of the door frame of the refrigerator, and a gasket clamped between said peripheral flanges of the frame sections.

11. A refrigerator door comprising complementarily formed inner and outer annular substantially L-shaped frame sections having portions overlapping transversely and longitudinally of the door, a gasket clamped between the portion of one frame section disposed longitudinally of the door and another frame section located transversely of the door, the transverse portion of one of the frame sections forming the periphery of the door, and a relatively thin finishing sheat'h for said periphery.

,12. A door designed to prevent heat transfer comprising an annular frame formed of complementary sections having portions overlapping transversely and longitudinally of the door, said flange when the door "is closed, said gasket be-. ing clamped between the flange of the frame section and one of the other frame sections and thereby held in place. i 1 13. A door designed to prevent heat transfer comprising an annular frame formed of complementary sections having portions overlapping transversely and longitudinally of the=d0or, said annular frame having a marginal flange formed by an extension of one of said'sections, a gasket disposed in a manner to be compressed by said flange when the door is closed, said gasket being clamped between the flange of the-frame section and one of the other frame sections and thereby held in place, concealed means for removably fastening said frame sections together, a transverse periphery of the frame forming a periphery of the door. and a relatively thin finishing sheath for said periphery.
